What is the scapula fracture

In the arm move the whole process, 2 / 3 of the activities took place in the shoulder, l / 3 of the activities take place in the chest wall between the scapula. Scapula chest wall Between the joint does not have the typical characteristics of the anatomical structure, but to provide functional equivalent of joint activities. In the rear clavicle and scapula directly connected with it. Collarbone fracture is the good of the whole body parts, but in comparison with its close neighboring, Both flat and thin little scapula fracture. Scapula fracture only body fractures O. 19 percent. The following reasons can explain this difference : ① scapula Although Chen Shui-bian thin, but obviously the edge of the bone thickening, therefore greatly enhance the strength of the bone itself. ② scapula in the chest wall On a lot of activity, forcing the scapula, the scapula because of the shift can be quite outside the buffer, thereby reducing The possibility of a fracture. ③ scapula the front and rear have huge muscles wrapping, before and after the formation of the "muscle cushion" to protect, First direct violence caused soft tissue injury, rather than a fracture. Scapula fracture, due to strong muscles wrapping, and generally do not fracture displacement, deformity was not obvious, and sometimes easily missed. Serious Composite injury, or patients in a coma, if not meticulous medical examination, but also easy to cause misdiagnosis. Clavicle and scapula addition to the two joint (acromioclavicular joint and sternoclavicular joint) and indirectly connected to the trunk, the direct connection of them muscle to complete. Because The chest wall between the scapula and a greater activity. Scapula Yu and humeral head of the shoulder, a hub of activities of the upper limbs. Scapula provide Shoulder muscles and ligaments of the beginning and end points. Shoulder is to maintain the foundation of stability, but also from the activities of a muscle leverage, so that the muscles Contraction play a more effective role.
